Optical microscopy techniques are primary analytical and descriptive tools for the petrographic analysis for all rock types (igneous, metamorphic and sedimentary), as well as unconsolidated materials (e.g. glacial deposits) and anthropogenic materials (e.g. cements and mine wastes). They are also essential for studying mineral deposits (ore minerals) and hydrothermal mineral alteration.

Detailed examination are made of thin sections and polished mounts using optical petrological microscopes, both in transmitted light and reflected light. Information obtained then enables or contributes towards mineral identification, textural analysis, diagenetic phase identification and sequencing, fracture and fault rock studies, modal analysis and porosity characterisation. In addition, UV epifluorescence microscopy is used for microbiological analysis of groundwaters and samples from laboratory experimental studies.

Staff and facilities are also in constant demand for direct consultancy analysis and interpretation by external clients including: oil, mineral and mining companies; engineering and utility companies; consultancies; university departments and local authorities.
